Some useful resources

For the entire course:

Intermediate Micro a Modern Approach (Varian) – Another book from Varian with a stronger focus on intuition and less on mathematics

Shan Akademy Youtube videos – Useful for self-study. Varian is covered and videos are on average 10 minutes and cover a specific topic, e.g., TRS

Youtubedia – http://youtubedia.com/ They have youtube videos and small handouts for for intermediate micro and mathematics for economists. For math “This course will cover basic university level mathematics. It is based on the book Essential Mathematics for Economic Analysis by Knut Sydsaeter, Peter Hammond, Arne Strom and Andrés Carvajal.”. This is from Lund University

Econgraph – https://www.econgraphs.org/textbooks/intermediate_micro/ It’s work in progress from Christopher Makler. Nice interactive graphs. E.g., here many  topics we covered in the first chapter, with nice graphs and examples: https://www.econgraphs.org/textbooks/intermediate_micro/scarcity_and_choice/production/

3Blue1Brown – https://www.youtube.com/@3blue1brown Great source for reviewing or leaning mathematical topics (calculus, linear algebra, etc). It has an emphasis on visualizing ideas.

For some topics:

What does the gradient vector mean intuitively? https://www.youtube.com/watch?v=H1DJjyDFalw
